Answer:
It's A=BH
Step-by-step explanation:
In the story the key words are there: Area, base/length, height
To find the volume of a rectangular prism, you just multiply the length x width x height.
So
1 1/4 x 4 x 3 1/4 = volume (and since they are all centimeters you don't have to worry about converting units)
You can also use decimals instead. So either the above equation or 1.25 x 4 x 3.25 = volume
and if you don't know the decimal for a fraction just pop it into a calculator if you have one, so to find 1/4 as a decimal just do 1 divided by 4 in the calculator. There are ways you can do it without a calculator but it's easier if you have one.
So the volume of this cube would be
16.25
or
16 1/4
Answers:
- In the top row, the first and third polygons are regular polygons.
- In the bottom row, only the first polygon is a regular polygon
============================================================
Explanation:
A regular polygon must have all sides of equal length. Also, all angles must be the same measure. This applies to the equilateral triangle in the upper left corner, and the square in the upper right corner. Each angle of the square is 90 degrees even though your teacher didn't use right angle markers.
The middle figure in the top row is not a regular polygon because the sides are not all the same length. Also, the angles are different.
--------------------
In the bottom row, only the first figure is a regular polygon for similar reasons mentioned earlier. The second figure is not a regular polygon because this figure is concave. Only convex polygons can be regular.
The third figure in the bottom row is not regular because one side is longer than the others.
Assuming you mean 2x to the 4th degree is 2x^4, the expression is 2x^4 + 5x.
And the value of that expression when x = 6 is:
2 (6^4) + 5(6) = 2 (1296) + 30 = 2592 + 30 = 2622
Answer: 2622
